Castillo Petruzzi et al v. Peru

On October 15, 1993, four Chilean citizens were arrested in Peru for terrorism. All four were members of the Tupac Amaru terrorist organization and were linked to several kidnappings. They were tried by a military tribunal while blindfolded and bound to chairs. None were allowed to examine the evidence against them or cross examine witnesses. They were all sentenced to life in prison. The Court found that the State violated the American Convention on Human Rights.
